[Sbs_software] [EXTERNAL] GEN Analysis Question - Accidental Background

[Sean Jeffas]

Hi All,

This is an open question for any GEN expert. We need to calculate the
accidental background contribution. For GEN-I this was done by using TOF to
calculate the velocity (beta). This is seen in my first picture below
(From_Freddy.png) taken from Freddy's thesis. In GEN-I they shift the data
away and take a cut of the events left and call this the accidental
background.

For GEN-II I am thinking that a similar concept for us is to look at the
coincidence time, and make a cut outside of the coincidence region. You can
see the red cut I made would be the region where we obtain the accidental
background events. Please let me know if anyone has other ideas or comments
on how this should be done.

Best,
Sean
